Best supplements for longevity

The boring, well-studied picks — not the biohacker of the month.

Longevity supplements get hype-cycled relentlessly. The picks with the longest safety record and broadest cardiometabolic evidence are, frankly, boring.

Omega-3s, vitamin D, creatine, and magnesium. Anything newer should be considered experimental.

Before you buy

  • VO2 max, strength, and sleep quality are better longevity predictors than any supplement. Train accordingly.
  • Be skeptical of anything marketed as 'anti-aging' with a paywall and a $200/month price tag.

Common questions

  • What about NMN, resveratrol, rapamycin?

    Interesting, under-researched in humans, and often expensive. Not on this list until the evidence catches up.
